President Harry Truman convened Congress in the summer of 1948. Nineteen forty-eight was an election year. Truman, a Democrat, had been promoting many progressive and forward-thinking policies. The Republicans, in an attempt to appear progressive themselves, tried to outdo Truman by proposing policies that some said were borderline socialistic. Truman called their bluff.
